24k Gold Sorapot auction to benefit Amit Gupta

Designer Joey Roth is auctioning a limited run of 24-karat gold Sorapots to help out BB pal Amit Gupta, who recently fell ill with leukaemia: "South Asians are severely underrepresented in the pool of registered bone marrow donors. 100% of profits from the auctions will go to drives, both here and in India, to find and register potential donors."

Materials listed: “24k gold, stainless steel, borosilicate glass” so I am guessing it is 24k plate or some other method of applying 24k over steel.
Also unless is is deceptively tiny a $200 starting bid for being fully 24k gold is unlikely.
